This page is intentionally left blank. Summary Summary The City of Morro Bay is extending the existing Harborwalk with continuation of a paved pedestrian boardwalk and separate Class I bike path from the existing parking area and crossing on Embarcadero Avenue northward. The City also proposes to install a clear-span pre-engineered/pre-fabricated bike and pedestrian bridge over Morro Creek to connect to north Morro Bay on Embarcadero Road/State Route 41. In addition, the project will include improvements to beach access from the trail, and two interpretive sign stations that will display educational and other information about the cultural and natural history of the region. This project is receiving funding from the Federal Highway Administration (FHWA) and with assistance from Caltrans. As part of its NEPA assignment of federal responsibilities by the FHWA, effective October 1, 2012 and pursuant to 23 USC 326, Caltrans is acting as the lead federal agency for Section 7 of the federal Endangered Species Act.

  • Unassisted Invasions: Understanding and Responding to Australia's High
    CSIRO PUBLISHING Australian Journal of Botany, 2017, 65, 678–690 Turner Review No. 21 https://doi.org/10.1071/BT17152 Unassisted invasions: understanding and responding to Australia’s high-impact environmental grass weeds Rieks D. van Klinken A,C and Margaret H. Friedel B ACSIRO, EcoSciences Precinct, PO Box 2583, Brisbane, Qld 4001, Australia. BCSIRO, PO Box 2114, Alice Springs, NT 0871, Australia. CCorresponding author. Email: [email protected] Abstract. Alien grass species have been intentionally introduced into Australia since European settlement over 200 years ago, with many subsequently becoming weeds of natural environments. We have identified the subset of these weeds that have invaded and become dominant in environmentally important areas in the absence of modern anthropogenic disturbance, calling them ‘high-impact species’. We also examined why these high-impact species were successful, and what that might mean for management. Seventeen high-impact species were identified through literature review and expert advice; all had arrived by 1945, and all except one were imported intentionally, 16 of the 17 were perennial and four of the 17 were aquatic. They had become dominant in diverse habitats and climates, although some environments still remain largely uninvaded despite apparently ample opportunities. Why these species succeeded remains largely untested, but evidence suggests a combination of ecological novelty (both intended at time of introduction and unanticipated), propagule pressure (through high reproductive rate and dominance in nearby anthropogenically-disturbed habitats) and an ability to respond to, and even alter, natural disturbance regimes (especially fire and inundation). Serious knowledge gaps remain for these species, but indications are that resources could be better focused on understanding and managing this limited group of high-impact species.

    A. Godinho Senior Thesis 1 Effects of Ehrharta erecta on the redwood understory and implications for restoration Anna Godinho Advisor: Ingrid Parker An undergraduate thesis for the Plant Sciences major in the Ecology and Evolutionary Biology Department of UC Santa Cruz 18 November 2013 A. Godinho Senior Thesis 2 ABSTRACT Biological invasions, particularly by exotic grasses, have the potential to reduce biodiversity and to alter ecosystem functions and disturbance regimes in native communities. Ehrharta erecta Lam. (panic veldt grass) is an evergreen perennial grass with life history traits that makes it an aggressive competitor against native species. It spread extensively beyond the sites of its experimental introduction around the central coast region of Northern California in the 1930s, and it has invaded the redwood understory on the UCSC campus. In my study, I compared photosynthetic rates of native species with and without the surrounding invader removed in order to gain insight into the physiological effect of E. erecta on native species. In a separate experiment, I compared the effectiveness of herbicide application and manual removal in controlling E. erecta on the UCSC campus. I evaluated how each treatment influences the recovery of natural communities by planting native redwood understory herb Clinopodium douglasii (Benthe.) Kuntze into treated plots, alongside unplanted controls, in order to examine 1) the effect of E. erecta removal treatments on native survival and growth rate 2) the effectiveness of native vegetation restoration in reducing reinvasion of E. erecta. A better understanding of the degree and mechanisms of impact of E. erecta on native species will serve to guide restoration priorities for invasive species management.
